I don't have much knowleged about Maple but following the help I was hoping I could solve the system of equations below. Any help is appreciated:

System of equations:

When the parameter of the Poisson distribution is less than

Statistics:-Sample(RandomVariable(Poisson(10^(-307))), 1)

or greater than

Statistics:-Sample(RandomVariable(Poisson(10^6)), 1),

error NE_REAL_ARG_LE or NE_REAL_ARG_GT appear, respectively.

Is there any way to remove or redefine these restrictions? Thanks.

Hi,

 i have 2 inequal plots i want to show in the same window:

with(plots):
p1 := inequal({x-y <= 1, x+y > 0}, x = -3 .. 3, y = -3 .. 3, optionsfeasible = (color = red)):
p2 := inequal({y < 0, x < 0}, x = -3 .. 3, y = -3 .. 3, optionsfeasible = (color = blue)): display(p1, p2);

Obviously, this doesn't work. Each single plot works. What can i do ?

Dear All,

I have been wondering about the reception of an independent patch Library for Maple.

I'll lay out a few ideas, and then maybe some criticism (or indifference) might follow.

I'm a bullet-point sort of person:

• sourceforge project with a few willing experts for vetting and gatekeeping of submissions.
• Patch .mla Library archive, going into /toolbox/Patch/lib/ so as to get picked up automatically by libname.
• Self-building, with...

A book had shown me using maple that if I solve({xbx+c=0},{x});

I would get x = (-b + sqrt(b^2-4ac)) / 2  and x = -b - ...    a normal way, the way everyone simplifies it as. 

However maple prints out  x = (-1/2) * (b-sqrt(b^2-4ac))/a  and the other x= ....

It is correct, however the formatting is ugly.  Why doesn't it show the same expression in the book which shows maple displaying it properly? 

Hello,

I have to build a simple procedure that will plot the graph and its tangent, however, i wanna go further and plot the x= (asymptot) if the function does not allow a derivative at a point. For instance, Tan(x) doesn't allow any derivative at Pi/2. I can't use the Showtangent command.

I would like to model the kinematics of a collection of points in R^3 - which represent atoms  on a molecule - using Maple. I want to specify the fixed distances between the points.  I just saw a formula in a book I own for the number of degrees of freedom of such a system. I wil have plenty of degrees of freedom with which to work. So, I will begin - in the simplest case - by arbitrarily specifying as many of the coordinates for the points as possible.

Does anyone have an idea of how best to program such a model?

I tried something like

Hello @all !

Well, we have a very strange? problem ...

Trying to export the formulas to C we receive the following error:

Error, (in analyzetab[_Inert_PROD]) cannot resolve types in {numeric, void}

The calculation(s) itself works fine in maple 11 and maple 10  but when we try to export the error appears.

So, can anybody help us ?

Any help is highly appreciated !!

Hi I was just wondering if there is a way to convert a mws file to a text file without maple? It is a uni holiday this week so I have no access to maple.

I was given a mws file as an example for an assignment and i want to rewrite it in c++ so i can run multiple trials on it automatically, but its really hard to work out whats happening viewing the mws in a texteditor. i havnt saved a maple program as text before but im assuming it will just be what my code is without any formatting info which is what im after.

Bonjour,

What is the key stroke for entering a subscripted name in 2D Math, Documentation Mode? For example, I'd like to enter V_BE as a name of a variable.  In the expression palette, I see a_n and a_*.  I know entering a_n is a_n. But now how do I enter a_* ? What is the key stroke in place of the question mark, a?*.  The Maple I am using is version 11. Thanks for the help.

i have this function:

f :=x-> ln(x^2) + 3*(x-2)^2;

i derivated it four times and i suppose that maple does something wrong (or i do ^^) with the fourth derivation. i made the derivation on paper and my results fit until the last derivation.

f'(x) = (2/x) + 6(x-2)  ok

f''(x) = (-2/x^2) + 6   ok

f'''(x) = (4/x^3)  ok

f''''(x) = (-12/x^4)  not ok <-- this is the maple result

if i derivated the third derivation on paper:

u = 4      v' = 0
